Patented June 23, 1936 UNITED STATES PATENT OFFICE WARP BEAM FrankMossberg, Attleboro, Mass., assignor to Mossberg Pressed SteelCorporation, a corporation of Massachusetts This invention relates to awarp beam and has for one Yof its objects the simplification of theconstruction of a warp beam and the provision of an opening extendingsubstantially the entire length of the beam for securing the warps inposition thereon by a batten or rod.

Another object of the invention is the spacing apart of thelongitudinally-extending edges of the beam and the provision ofsupporting disks l0V which are shaped to cooperate with the spaced edgesfor the reception of a fastening rod or bar for locking the warps inposition.

Another object of the invention is the utilizing of the end supportingdisk for mounting a friction drum or pulley in position at the end ofthe beam.

Another object of the invention is the provision of an adjustable headwith a disk and supporting hub extending from the outer surface of thedisk and with outwardly-extending supporting ribs, the same being soformulated that the hub may be contracted about the barrel of the beamfor holding it in the desired adjusted posi-v tion.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims..

In the formation ofA warp beams, it is sometimes desirable to simplifythe structure; and in order that this may be accomplished I have formeda construction in which the edges of the barrely of the beam are spacedand the beam supported by 55 disks which are notched so that a battenwhen inserted between these spaced edges may be received in the notchesof the disk and by reason of its width will bind a set of warp threadsagainst one of the edges of the barrel to hold the warps secured theretofor winding them upon the beam, and I have utilized the end supportingdisk for mounting a friction pulley and have also provided a head havinga hub with supporting ribs, which hub even when so supported by ribs maybe contracted upon the beam to secure the head in adjusted position; andthe following is a detailed description of the present embodiment ofthis invention illustrating the preferred means by which theseadvantageous results may be accomplishedr- With reference to thedrawing, I have shown the beam as composed of a barrel I0 which isrolled up from sheet stock with its edges I I and I2 spaced a certaindesired distance, as illustrated in Fig. 2. This barrel is supported inthis position by means of disks-l3 spaced at suitable distances alongthe body and welded to the inner surface of the barrel. Each disk isprovided with a notch I4 which will have its opposite sides I5substantially parallel and parallel to a perpendicular to a tangent tothe outer surface of thev cylindrical barrel at the center of the recessI4. This notch is provided with a bottom I6 at right angles to the sidesand the notch is of a width and depth sufficient to receive a batten orrod I'I winch is of such a size relative to the spaced edges I I and I2asto bind the warps inserted into the space against one of the edges I Ior I2 and securely hold a sheet of warps in position along the barrel.The notch I4, of course, in the disk limits the amount of insertion ofthe rod and thus prevents it from extending inwardly beyond the edges IIor I2 that the gripping action may be lost at points between the disks.

In some instances, I may, however, provide a bottom wall I8 in the formof a strip or ribbon extending from one disk to another and located inthe notches thereof against the bottom I6 to provide' a bottom wall forthe opening or recess between theedges II and I2 for limiting theinsertion of the rod and also providing a surface against which thewarps may be bound, which structure I have illustrated in Figs. 6 and 7.

A friction pulley 20 .is mounted upon each end of the beam and isprovided with a recess 2| of a size to fit the barrel I0 to center itwith respect to the barrel and this friction pulley is secured in thispositionby meansv of' bolts -22 extending thru a web portion 23 of thefriction drum and into the tapped openings 24 in the end disk 25,

which securely binds the pulley in position on the end of the warp beam.Each of these pulleys is provided with a trunnion or spindle 26supported in a hub 46 extending thru an opening 41 in the end disk 25for suitably mounting the beam for rotation in any convenient bearings.

Adjustable heads designated generally 30 are mounted on the barrel, eachof which consists of .a fiat disk 3| to which there is welded a. hubcomprising a band or collar 32 having ,a flange 33 extending outwardlytherefrom, which hub and flange are welded to the outer surface 34 ofthe disk 3|, while leaving the inner surface 35 perfectly smooth andclear for engagement with the warps. In order to better support this huband also stiffen the disk 3| against warping or being l distorted fromshape, I provide ribs 36 extending outwardly such as illustrated in Fig.5. Each of these ribs is welded to the hub and flange and also to theouter surface 34 of the disk. This hub 32 is provided with a threadednut 31 at one end and an inner threaded ear 38 at the other end while abolt 39 extends thru the ear 38 and is in threaded engagement with theear 31 to draw these ears together, turning of the bolt beingaccomplished by the polygonal head of the bolt.

In order, however, that the hub and flange may be contracted, I haveprovided a slot 45 extending from the opening between the ears 31 and 38to ie point 4| to space the hub and iiange from the outer face 34 of thedisk and I have carried this slot into the rib 42 outwardly as far asthe dotted line 43 in order to permit this inner portion of the rib toflex with reference to the disk thus upon contraction by the bolt 39that portion of the hub between the dotted line 4| and the ear 31 williiex and the rib 42 will also flex to permit contraction of the warp forbinding the head in position along the warp beam after the properadjustment between the heads has been obtained. V

In Fig. 8, I have illustrated a still further modified construction ofbarrel and recess. A full channel 5G is positioned in the notches in thedisks with its bottom wall 5| resting on the bottom |6 of the notchesand with its side walls 52 positioned beneath the edges and |2 of thebarrel. This channel may thus be held in without welding throughout itslength or by welding only at its ends.

The foregoing description is directed solely ,towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being deiined and limited only by theterms of the append-V ed claims. v
